    tweaking my Bright house networks connection

    Hey Guys,

    I'm looking for some help tweaking my connection. I'm running XP with a 2.2Ghz and 512mb. Any help will be appreciate. Thanks in advance

    TCP options string = 020405b40103030201010402
    MTU = 1500
    MTU is fully optimized for broadband.
    MSS = 1460
    Maximum useful data in each packet = 1460, which equals MSS.

    Default Receive Window (RWIN) = 256960
    RWIN Scaling (RFC1323) = 2 bits (scale factor of 4)
    Unscaled Receive Window = 64240

    RWIN is a multiple of MSS
    Other values for RWIN that might work well with your current MTU/MSS:
    513920 (MSS x 44 * scale factor of 8)
    128480 (MSS x 44 * scale factor of 2)
    64240 (MSS x 44)
    bandwidth * delay product:

    Your RcvWindow limits you to: 10278.4 kbps (1284.8 KBytes/s) @ 200ms
    Your RcvWindow limits you to: 4111.36 kbps (513.92 KBytes/s) @ 500ms
    MTU Discovery (RFC1191) = ON
    Time to live left = 56 hops

    TTL value is ok.
    Timestamps (RFC1323) = OFF
    Selective Acknowledgements (RFC2018) = ON
    IP type of service field (RFC1349) = 00000000

    Looks dark
    Looks good. Nice basic tweak. You might try 64240 for the RWIN and see if that changes anything with respect to your speeds.

    How are your speeds?
    People will forget what you said... and people will forget what you did... but people will never forget how you made them feel.

    Try the following in cablenut which is below me

    DefaultReceiveWindow = 256000
    DefaultSendWindow 49152
    DisableAddressSharing = 1
    InitialLargeBufferCount = 200
    InitialMediumBufferCount = 480
    InitialSmallBufferCount = 640
    LargeBufferSize = 81920
    MaxFastTransmit = 64000
    MediumBufferSize = 15040
    PriorityBoost = 0
    SmallBufferSize = 1280
    TransmitWorker = 32
    FastSendDatagramThreshold = 4096
    EnableFastRouteLookup = 1
    EnablePMTUDiscovery = 1
    IgnorePushBitOnReceives = 0
    GlobalMaxTcpWindowSize =52560 or 64240
    MaxFreeTcbs = 8000
    MaxHashTableSize = 16384
    MaxNormLookupMemory = 5000000
    SackOpts = 1
    SynAttackProtect = 1
    Tcp1323Opts = 0
    TcpLogLevel = 1
    TcpMaxDupAcks = 3
    TcpMaxHalfOpen = 100
    TcpMaxHalfOpenRetried = 80
    TcpRecvSegmentSize = 1460
    TcpSendSegmentSize = 1460
    TcpTimedWaitDelay = 30
    TcpUseRFC1122UrgentPointer = 0
    TcpWindowSize =52560 or 64240
    MaxConnectionsPer1_0Server = 20
    MaxConnectionsPerServer = 10
    DefaultTTL = 64
    DisableUserTOSSetting = 0
    TcpMaxDataRetransmissions = 6
    DefaultTOSValue = 92

    Make SURE you follow these important tips as well:

    1. Open Internet Explorer and select Tools - Internet Options - under the General tab in the Temporary Internet files section select the Settings button.

    Select "Every visit to the page" and set the amount of disk space to use: to no more than 80MB. Now select the Connections tab and select LAN Settings make sure EVERYTHING there is unchecked and select OK.

    2. For IE6 ONLY - select the Privacy tab and choose Advanced check the box "Override automatic cookie handling" and for First-party Cookies - Accept, Third-party Cookies - Block and check "Always allow session cookies. Now NO MORE SPYWARE COOKIES.

    3. Another thing to do about once a week if you modem is on 24/7 is to power cycle your modem, just completely disconnect power from it for atleast 15 seconds and then power it back on.

    4. Set your temporary internet files to 80mb and delete them regularly.

    5. DSL users may want to check out the DSL Wiring Guide for possibly increasing your DSL speed.

    6. By default Windows 2K & XP cache everything in the DNS cache service, both correct and faulty DNS lookups. To increase performance by eliminating the caching of faulty DNS lookups, change the following values from whatever their original values are to zero.


    7. Always connect your modem via ethernet (Network Interface Card) instead of USB, ethernet is faster and much more stable. Also ALWAYS make sure you have the latest drivers for your NIC from the manufacturer NOT Microsoft, alot of times the drivers from the manufacturer have advanced settings that help optimize the performance of your NIC that the native Microsoft drivers don't have.

    8. Scan for spyware weekly with Ad Aware & SpyBot

    9. Make sure you have the latest drivers for your NIC from the manufacturer. If you are using a router make sure you have the latest firmware.

    10. For 2K & XP - Under your LAN connection - properties - general tab, uninstall all the protocols there that you do not need.

    For 98 & ME - Under your Configuration tab for your Network settings make sure you have only the needed protocols and install the vtcp 386 patch and the NDIS Update from here
